​Office Anesthesiology & Dental Consultants, PC (OADC) was established over 20 years ago by Dr. Zak Messieha, a dentist anesthesiologist.  He sensed the need for high quality office-based anesthesia care.  Office-based and ambulatory anesthesia care is the fastest growing segment in surgical anesthesia.  OADC is committed to the provision of such care in a safe,  state-of-the-art model to meet such need.  As part of the commitment to continuous improvement in quality and maintenance of the highest standards of care, Office Anesthesiology, voluntarily, goes through an accreditation process with the Accreditation Association for Ambulatory Health Care, Inc. (AAAHC), a Nationally-recognized accreditation organization, thus becoming the first dentist anesthesiologist-run mobile anesthesia practice in the USA to be accredited by the AAAHC.

Let us fulfill your anesthesia needs.
